Update strace to 4.19.
Noteworthy changes in release 4.19 (2017-09-05)
===============================================
* Changes in behaviour
* Changed formatting of personality names on tile architecture in order
to make it in line with other multi-personality architectures.
* Changed field output order in struct v4l2_requestbuffers to improve in/out
field formatting.
* Changed handling of multiple signal= specifications in an injection
expression: multiple specification now leads to error instead of implicit
usage the last specification.
* Improvements
* Enhanced decoding of optlen argument of getsockopt syscall.
* Enhanced decoding of SO_LINGER option of getsockopt and setsockopt syscalls.
* Enhanced decoding of SO_PEERCRED option of getsockopt syscall.
* Enhanced decoding of IP_ADD_MEMBERSHIP, IP_DROP_MEMBERSHIP,
IPV6_ADD_MEMBERSHIP, IPV6_DROP_MEMBERSHIP, IPV6_JOIN_ANYCAST,
IPV6_LEAVE_ANYCAST, MCAST_JOIN_GROUP, and MCAST_LEAVE_GROUP options
of setsockopt syscall.
* Enhanced decoding of KEYCTL_DH_COMPUTE operation of keyctl syscall
(KDF parameters decoding).
* Implemented decoding of KEYCTL_RESTRICT_KEYRING operation of keyctl syscall.
* Enhanced decoding of UFFDIO_API ioctl command.
* Enhanced decoding of BPF_PROG_LOAD, BPF_MAP_CREATE, BPF_MAP_LOOKUP_ELEM,
and BPF_MAP_GET_NEXT_KEY commands of bpf syscall.
* Implemented decoding of linux socket filter programs specified
for SO_ATTACH_FILTER and SO_ATTACH_REUSEPORT_CBPF socket options.
* Implemented decoding of inet_diag_req_v2, inet_diag_req_compat,
packet_diag_msg, and smc_diag_msg netlink attributes of NETLINK_SOCK_DIAG.
* Implemented NETLINK_SELINUX protocol specific decoding.
* Implemented decoding of netlink message ack flags.
* Implemented decoding of nlmsgerr netlink attributes.
* Implemented basic protocol specific decoding of NETLINK_CRYPTO.
* Implemented decoding of crypto_user_alg netlink attributes
of NETLINK_CRYPTO.
* Implemented basic protocol specific decoding of addr, addrlabel, dcb, link,
mdb, neigh, neightbl, netconf, nsid, route, rule, tc, and tca messages
of NETLINK_ROUTE.
* Implemented decoding of NETLINK_KOBJECT_UEVENT messages.
* Improved handling of unexpected tracees (the ones that cloned with
CLONE_PARENT/CLONE_PTRACE or called PTRACE_TRACEME on themselves): they
are now PTRACE_DETACH'ed instead of PTRACE_CONT'ed.
* Updated lists of BPF_*, KEY_*, RWF_*, SCM_*, SO_*, and *_MAGIC constants.
* Added decoding of arch_prctl syscall on x86.
* Added decoding of seccomp, bpf, userfaultfd, membarrier, mlock2,
copy_file_range, preadv2, pwritev2, and statx on alpha.
* Added decoding of statx syscall on microblaze.
* Added decoding of s390_guarded_storage syscall on s390.
* Updated lists of ioctl commands from Linux 4.13.
* Enhanced manual page.
* Bug fixes
* Fixed printing of group_req structure on non-native personalities.
* Fixed output formatting of blkpg_ioctl_arg, dm_name_list, and iocb
structures.
* Fixed formatting of nul-terminated strings which have kernel-imposed size
limit.
* Fixed printing of paths that hit PATM_MAX limit in order to match kernel's
behaviour.
* Fixed build warnings on Android mips64.
* Fixed unused function "is_negated_errno" build warning when built
with clang.
* Fixed syscall number and arguments retrieval behaviour on sparc64 and
mips o32 after prctl(PR_SET_DUMPABLE, 0) makes PTRACE_PEEKTEXT impossible
to use if Linux kernel has commit v4.10-rc1~114^2~2.
* Fixed path tracing for execveat, symlink, symlinkat, inotify_add_watch,
and inotify_init syscalls.
* Fixed personality switch printing on sparc64 and risc-v.
